Rotor

Rotor is an API-only LLM gateway. It exposes OpenAI-compatible, Anthropic-compatible, and basic OpenAI Responses-compatible endpoints over the models and provider keys configured as channels.

Rotor includes a minimal browser admin page at /. Management can also be done directly through HTTP admin APIs.

Run

cd /Users/whoami/research/apirouter/rotor
pip install -e .
rotor serve --host 0.0.0.0 --port 8000

Open the admin page:

http://localhost:8000

By default, Rotor stores runtime files in ~/.cache/rotor:

~/.cache/rotor/
  rotor.db
  conversations/

Important Environment

# Optional. Defaults to sqlite+aiosqlite:///~/.cache/rotor/rotor.db
DATABASE_URL=
# Optional. Defaults to ~/.cache/rotor/conversations
CONVERSATION_STORE_DIR=

Configure Channels

Each channel stores one provider base URL, provider API key, supported models, priority, and weight.

curl -X POST http://localhost:8000/api/admin/channels \
  -H "Content-Type: application/json" \
  -d '{
    "name": "zhipu-main",
    "type": "zhipu",
    "key": "provider-api-key",
    "base_url": "https://open.bigmodel.cn/api/paas/v4",
    "models": ["glm-4.7"],
    "model_mapping": {},
    "priority": 10,
    "weight": 1,
    "enabled": true,
    "protocol": "openai"
  }'

base_url is the upstream provider API root. key is that provider's API key. Different providers or different keys should be configured as separate channels. Channels serving the same model are distributed by priority and weight.

Generate User API Key

curl -X POST "http://localhost:8000/api/admin/tokens/generate?name=demo&quota=1000000" \

Use the returned key against Rotor:

curl -X POST http://localhost:8000/v1/chat/completions \
  -H "Authorization: Bearer $ROTOR_API_KEY" \
  -H "Content-Type: application/json" \
  -H "X-Conversation-Id: conv_demo" \
  -d '{
    "model": "glm-4.7",
    "messages": [{"role": "user", "content": "hello"}]
  }'
